' 2 Application filed July 28, 1896. Serial No. 600,767. (No model.)

To ctZZ whom it may concern:

Be it knownj that I, CHARLES V. Born, a

citizen of the United States, residing at Lancaster, in the county ofLancaster, State of Pennsylvania, have invented certain Im provements inTrack-Sanders, of which the following is a specification.

This invention relates to improvements in that class of devices employedfor sanding railway-tracks, more particularly the tracks of railways onwhich electrical cars are used;

and the objects of theimprQVementsare, first,

toprovide more especially for a continuous and uniform feed of damp orwet sand to the. rails; second, to regulate the quantity of sand fed tothe rails; third, to remove stones and large gravel from the sand as itis'fed t0 the track, and, fourth, 'to prevent undue noise by theoperating parts The sanding of the tracks of electric railways isabsolutely necessary to the running of cars in cities'and townsduringwet weather, for the reason that the rails become so covered withslime and mud of the streets that it is impossible forthe'driving-wheels to take hold of the rails with0ut the aid of sand.This necessity for sanding the tracks is so great that in the largercities special sandingoars are run at intervals between the regulartraffic cars, and the mechanism for feeding the sand'therefrom to therails has heretofore been so unsatisfactory that with many roads thesand is fed through chutes directly to the rails by hand-shovels. Mydevice feeds sand to the track steadily and uniformly.

t My invention is'illustrated in the accompanying drawings, forming apart of this specification, and in which-- Figure 1 is a side elevationof a sander embodying my invention and shown attached toa sand-can: Fig.2 is a top plan View of the frame supporting the sand-box; Fig. 3, a

chute.

Fig. 11 is a perspective View show-' ing theposition of the parts when the center brush is engaged with itscam-wheel; Fig. 12, a similar view, but showing the position of theparts when the outer brushes are engaged with their cam-wheels; Fig. 13,a perspective inner face view of one of the bearing-plates of the'agitating-shaft; and Fig. 14, a similar View of the rear plat-e,carrying the stop for the center brush. Fig. 15 is a vertical section ofthe adjusting mechanism for the vibrating end of the sand-box. Fig. 16is a transverse section on broken line 16 16 of Fig. 1, showing theconnection between the frame and the case inclosin g the operatingmechanism.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicates the fioor of thecar, on which the frame supporting the sand-box rests; Afa track wheel;A", the axle of said wheel, through which the operating mechanism isdriven, and A the rail.

The frame supporting the sandbox comprises a base having horizontalcheeks B, connected by front and back plates B B respectively, and armsB extending upward and backward and connected 'by a cross-bar b. Onfront plate B are ears Z), through which pass bolts securing the frameto the floor of the car. The bottom of the frame is open; but on cheeksB are inwardly-projecting plates b on theends of the parallel edges ofwhich are depending lips 19 through which the case containing'theoperating mechanism is supported, as will be described, and in plates bare bolt-holes I), through which pass additional bolts for securing theframe in place. Plates b are braced by transverse bars b and brackets bA transverse rod B is supported in bearings 19 on the upper ends of armsB A D indicates an inclined sand-box having in its lower end adelivery-opening d, and on the bottom of said sand-box aredownwardlyextending rocking arms D, through eyes d in the lower ends ofwhich passes the stationary shaft B Arms D are located behind the centerof the sand-box, the rear end whereof extends back of said rod B and onthe bot- 'tom of said sand-box and in front of the ceuter thereof aredepending ears (Z having wrist-pins (Z on their outer faces, which areengaged by the upper ends of connectingrods D to be described.

Beneath the base of the frame just described is located the ease inwhich is housed the mechanism through which the sand-box is actuated,and there are on the top thereof upwardly-extending lips c, bolted tothe lower portions of connecting-plates E, the upper portions of whichare in like manner bolted to depending lips I) of the frame-base. Thiscase comprises an upper rectangular chamber E and a lower semicircularchamber E The chamber E has vertical flanges c" offset from itslongitudinal edges and within which the edges of chamber E rest. On thesides of the longitudinal meeting edges of these chambers are horizontallugs 6, those of chamber E passing through openings in flanges c" andthrough lugs The chambers are secured together by bolts 6. In the sidesof chamber E are annular openings 0 having oppositely-locatedrectangular wings c and in the back of said chamber E is an oval openinga Annular openings 0 are engaged by similarly-shaped bosses F, havingthereon rectangular wings F, that engage the corresponding wing-openings6 The bosses F are formed with plates F that bear against the faces ofthe sides of the chamber and have wings F through which they areremovably secured to said sides. The wings F of the bosses F are formedwith plates F and their wings F Through these annular bosses and platesare upright circular-ended slots I ,that incline somewhat from thebot-tom upward toward the front of the chamber, and on the upper rearportions of the faces of said bosses are stops F, having inner nprightlyand outwardly inclined faces f. Oval opening 6 is engaged by asimilarly-shaped boss F", and said boss F is formed with a plate F thatbears against the back of chamber E and has wings f, through which it isremovably secured to said back. On the inner face of boss F is ahorizontal channeled lip f, in which is adjustably secured aninwardly-extending stop f by means of a set-screw f, working through anopening in said step and a slot in the bottom of said channel. SlotsFform bearings for the spindles g of a revoluble reciprocating rod G,passing through said chamber E, and to the extremities of these spindlesare attached the lower ends of connecting-rods D the upper ends of whichengage pins (1 of the ears on the bottom of the sand-box, as described.On the center of bar G is fixed a rigid brush G, which llares outwardfrom its intersection with the rod longitudinally thereof, so that ithas a broad outer contactface g. On each side of brush G and adjacent tospindles g are similar brushes G set approximately at right angles withbrush G, and 011 the side of said rod opposite to brushes G and alsoadjacent to spindles g are studs In the end walls of chamber E isjournaled a shaft II, having on its outer end a sprocketwheel I,connected by a sprocket-chain I with a sprocket-wheel l on axle A oftrack-wheel A. On the center of shaft II is a wheel 11, registering withbrush G and having a series of cams formed on and entirely around itsperiphery. Each of these cams has an inclined face 7L, a short flattenedapex 7L, and a shoulder 7L2, the face of which is in a radial plane tothe axis of shaft II, the inner edge of each shoulder coinciding withthe inner edge of the inclined face 7t of the succeeding cam. On eachside of cam-wheel ll is a similar wheel H registering with brushes G andhaving the cams thereon set in a direction opposite to that of the camson wheel 11. \Vhen the car is moving to the rear, center brush G engagescenter cam-wheel ll, reciprocating rod G in slots F, the tendency of thecams on said wheel to revolve brush G backward being overcome by stopf", the extremity of which bears against the rear face of said brush G.lVith the reversal of the movement of the car the shoulder adjacent tothe cam on which brush G rests engages said brush and throws it upwardand forward, revolving rod G and throwing side brushes G into contactwith side cam-wheels 11 whereby red G is reciprocated in the same manneras when brush G engaged cam-wheel 11. Side brushes G are prevented frombeing swung forward by cam-wheels 11 by the engagement of studs g on redG with steps 1 on bosses 1*.

The pounding of the brushes as they engage successively with theinclined faces of the cams produces, normally, a rapid and loudsuccession of reports that are exceedingly objectionable. This Iovercome by filling the lower portion of chamber E with thick heavy oil0, known to the trade as cylinder-stock. l commonly fill thecylinderwith this oil up to the journals of shaft ll. The oil is caughtup by the cam-wheels, and so coats the surfaces of the same as to form acushion thereon and completely deaden any sound that would otherwise beoccasioned by the hammering of the brushes on said wheels. I do notconfine myself to the use of cylinder-stock for this purpose, as anyother unctuous or sticky matter that will accomplish the same result maybe employed.

011 the lower end of the sand-box are posts d having horizontal slotstherein, which are engaged by tongues Z on the head L of a toothedbreaker and sieve acting in conjunction with delivery-opening (Z in thebottom of the sand-box. In head L is a set of long breaker-teeth L, thatextend diagonally downward across delivery-opening cl and have theirends resting on the bottom of the sand-box above said delivery-opening.That part of the shanks Z of breaker-teeth L adjacent to head L andextending across delivery-opening (Z are narrow and sharp, with widespaces between them; but inside of said delivery-opening they arewidened out topresent broadflat sides Z uppermost. From said widened-outportion the. teeth taper to the inner ends, which are pointed and havetheir upper sides beveled, as shown at Z To the head L or to-the partsof teeth L adjacent thereto are attached the shanks M of sieve-teeth M.These shanks extend die agonally downward 'and forward to or near to thefront wall of the sand-box, and somewhat above the frontend ofdelivery-opening d shanks M are connected by curves m with saidsieve-teeth, which extend through deliv ery openin g d back beneath thesand-box and have their ends projecting over the back plate B of thebase of the supporting-frame, so as to deliver onto the car-floor behindsaid'frame any matter passing over them. The sieveteeth M are connectedby transverse bars, 'm and are more numerous than breaker-teeth L, beingso arranged that there shall be a sieve-tooth below each breaker-toothand one below the center of each space separating said breaker-teeth.The object of this construction is to break up all lumps or masses ofsand delivered to the rail and to separate large-sized stones or gravelfrom the sand.

These sanding-machines are generally used in wet weather, when thetracks arewet and slippery and when the sand itself is moist, heavy, andsticking together in masses,for it is to be remembered that it is notfine sharp sand that isns'ed for this purpose,'but,the inferiorqualities, in which is mixed loam and other earthy matter andimpurities. This'san'd is loaded into the upper end of the sand-box,whenceby the vibration thereof, to be de: scribed, it works down to thebreaker-teeth L. The finer parts pass between the points of said teethand down through delivery:-

opening d into chute D, whence it is. discharged to the rail. The, lumpsand masses of sand and gravel, however, are carried over thebreaker-teeth until they reach the nar row sharp parts Z thereof, wherethey are more or less split and broken andfa-ll down ontothe'sieve-teeth M, which completes the separation of the particles andallows the same to pass down into chute D the stones and gravel toolarge to pass between said teeth M being carried back and deposited, onthe floor of thecar, behind the supporting-frame." By

- having the breaker-teeth widened from the points to the narrow-edgedparts Z the lumps are carried to vthe greatest possible height abovesieve-teeth M, so that they may be more vcompletely disintegrated by thegreater force with which they strike said sieve-teeth.

To front plate B ofthe supporting-frame is secured a plate'N, connectedby a neck nwith a socket-base N, and to the front of the sand-box issecured a plate P, connected by a neck 19 with a cylindrical cap P. Inthe up. per part of, base N isa socket n, and through a threaded openingn in the lower portion of said base passes an adjustingmodR, having athreaded section 7" thereon that engagesthe sand-box.

thread-of said opening. The rod R'extends up into cap P and has a head Rsecured thereon by a countersunk screw 1", said rod being actuatedthrough a hand-Wheel R on the lower end thereof. The upper end ofthreaded section 1 of rod It forms an annular shoulderon which rests awasher W, that plays vertically in socket n with'the up-anddown motionof said rod R, and on said washer rests the lower end of a rubber orother elastic sleeve S, that encircles the stem of rod R and has itsupper end-bearing against the bottom plate 1) of cap P, which itsupports. In the chamber P of cap P is a spring S,

coiled around the upper end of rod R and having its lower end resting onbottom plate 19 and its upper end bearing againsthead R of said rod R. p

a In Fig. 1 is illustrated a mechanism for temporarily stopping thevibration of the On the front of the lower part of cap P is formed aforwardly-projecting lug T, having its end rounded, as shown, and on thefront of the top of base N and ranging with lug T are two jaws T.Between jaws T is f ulcrumed a cam-lever, which com prises a handle Vand a cam-ended arm V. In its normal position the end of handle V restson shown and described is simple and effective.

In operating motion is transmitted from track-wheel axle A throughsprocket-wheels I I and sprocket-chain I to shaft H, and from said shafta vertical reciprocating move: ment is imparted to rod G through thecamwheels H or H and brushes G or G and this movement of rod G iscommunicated to the sand-box through connecting-rods D attached theretoin front of its pivotal c'onnec tion with stationary shaft 13, thusvibrating the sand-box vertically and working any sand therein down tothe breaker andsieve-teeth and through delivery-openingd into chute Dwhence it is deposited on the rail A The vertical play of the lower endof the sandbox is regulated by the mechanism located in socket-base Nand cylindrical cap P. When this play is to be lessened, the adjlisting-rod R is screwed down, thus compressing spring S and shorteningthe movement of said cap P, and when the vertical play of the sand-- boxis to be increased the adj usting-rod R is screwed up, allowing greaterlength of move ment between the ends of spring S. The elastic sleeve Sserves as a cushion to break the shock of impact of the parts.

Other means may be employed As will be" IIC understood, there is one ofthese traeksanders on each side of; the car, so as to feed to both linesof rails of the track.

I do not restrict myself to the details of construction of the variousparts shown and described, as it is obvious that many alterations maybemade therein without departing from the spirit and scope of myinvention.

My invention involves a radical departure in the construction andprinciple of operation in sanding-machines and in the mechanismconnected therewith, the invention consisting, broadly, in a device forimpartin g a vertical vibration to the sand-box as the sander is movedeither forward or backward in forming a cushion on an actuating part ofthe mechanism by passing the same through unctuous or other stickymatter and in providing a resilient support for a vibrating end of thesand-box.
